2017-08-21arm64: zynqmp: Add generic compatible string for I2C EEPROMJavier Martinez Canillas1-2/+2
The at24 driver allows to register I2C EEPROM chips using different vendor and devices, but the I2C subsystem does not take the vendor into account when matching using the I2C table since it only has device entries. But when matching using an OF table, both the vendor and device has to be taken into account so the driver defines only a set of compatible strings using the "atmel" vendor as a generic fallback for compatible I2C devices. So add this generic fallback to the device node compatible string to make the device to match the driver using the OF device ID table.

2016-09-14Merge branch 'dt/irq-fix' into next/dt64Arnd Bergmann1-4/+4
* dt/irq-fix: arm64: dts: Fix broken architected timer interrupt trigger This resolves a non-obvious conflict between a bugfix from v4.8 and a cleanup for the exynos7 platform.
2016-09-14arm64: dts: Fix broken architected timer interrupt triggerMarc Zyngier1-4/+4
The ARM architected timer specification mandates that the interrupt associated with each timer is level triggered (which corresponds to the "counter >= comparator" condition). A number of DTs are being remarkably creative, declaring the interrupt to be edge triggered. A quick look at the TRM for the corresponding ARM CPUs clearly shows that this is wrong, and I've corrected those. For non-ARM designs (and in the absence of a publicly available TRM), I've made them active low as well, which can't be completely wrong as the GIC cannot disinguish between level low and level high. The respective maintainers are of course welcome to prove me wrong. While I was at it, I took the liberty to fix a couple of related issue, such as some spurious affinity bits on ThunderX, and their complete absence on ls1043a (both of which seem to be related to copy-pasting from other DTs).
